Zing Along with Mitch: The Reaganite new budget chief.

In the 19th century, the Secretary of War occupied a three-room suite on the second floor of what is now the Eisenhower Executive Office Building, adjacent to the White House on Pennsylvania Avenue. But since 1939, the ornate quarters have housed each administration's budget director, including such notables as George Shultz, Caspar Weinberger, Bert Lance, and David Stockman. It is now Mitch Daniels who cordially greets visitors to the offices of the director of the Office of Management and Budget, where he will be waging war against high taxes- and congressional spending binges-on behalf of a president whom Daniels describes as "resolute" in his determination to control federal spending. Mitch Daniels's own determination is underscored by his recognition that before the year is out, the administration could have a civil war on its hands with a spendthrift Republican Congress.

Returning to Washington from the corporate world in Indianapolis, Daniels feels like "a reservist called up for active duty," and his old conservative colleagues are delighted that President Bush sounded the call for this veteran of the Reagan White House. "Mitch's appointment is a total home run," in the opinion of Stephen Moore, who has left the Cato Institute to run the Club for Growth, a free-market advocacy group on whose board Daniels served along with Arthur Laffer, former Delaware governor Pete DuPont, National Review contributing editor Lawrence Kudlow, and NR president Thomas L. "Dusty" Rhodes. Daniels, says Moore, is "very much a supply-sider" and "as eloquent as anyone in the administration on tax cuts."

The new OMB director himself describes his political philosophy succinctly, varying only the modifiers: "I'm a Reagan conservative, I'm a Lugar conservative, I'm a Bush conservative." He is now in unfriendly territory, and acquitting himself well. On a recent Sunday-morning TV show, Daniels made the case for the president's budget agenda, in a match-up with Sen. Joe Lieberman. When challenged on whether Bush's pessimism about the economy was intended to build support for his tax cut, Daniels replied, "Well, that would be a pretty good reason, by the way," and pointed out the historically high level of income taxes. When asked about the administration's view of a proposed "trigger" to halt tax cuts if the surplus shrinks, Daniels called the idea-promoted by some GOP senators-unnecessary and unwise, noted that taxpayers' interests always seem to come last, and wondered why there was no mechanism to slow spending in the face of an economic downturn.

Former congressman David McIntosh, an Indiana Republican, credits Daniels-"one of the smartest people I've ever met"-with the fact that Washington's current budget debate so favors Republicans. He points out that Daniels, who cochaired McIntosh's unsuccessful campaign for governor last year, put together a budget for the president that supported his tax cuts without making the kind of program cuts that would provide Democrats with ammunition against the plan.

As a veteran GOP political strategist, Daniels has engaged in most of Washington's major debates over the last few decades. Following his 1971 graduation from Princeton, he returned home to Indianapolis to work for Mayor Richard Lugar. After Lugar's 1976 election to the Senate, Daniels joined him in Washington, where he became the senator's chief of staff, and finished his law degree at Georgetown University. During the 1984 election cycle, Daniels ran the Republican Senate campaign committee, and then served in the Reagan White House, first as liaison to state and local officials, and later as political director.

In Daniels's view, Reagan was the kind of great political leader who, in Disraeli's words, "knew himself and knew his times." He talks about Reagan's "sunny disposition, his resolution, and his unwavering concentration on the big issues." Here, he sees some similarities with his current boss: "President Bush has a superb balance in terms of management style. He's very engaged with the things that matter, but he will not be distracted by the trivial." The "Hoosier modesty" his ...
